Abstract
Introduction: Median nerve compression is the most common nerve entrapment syndrome. After carpal tunnel release, patients often complain about the scar cosmetic appearance. Objective: The aim of our study was to evaluate the clinical outcome, surgical technique and complications of mini-open carpal release. Methods: We reviewed data from 48 surgical procedures for Carpal Tunnel Syndrome in 32 patients at the Pinheiros Neurologicaland Neurosurgical Clinic in the period of 2000 and 2008. The mean age was 49 years-old. We used a 2 cm incision and microscopic technique to obtain meticulous access of the palmar hand anatomy with special attention to both the recurrent motor branch and palmar cutaneous nerve. Results: Twenty-two patients had total resolution of symptoms. Two patients had no change of neurological symptoms. During the follow up no infection or neurological deficits were observed. Conclusion: Mini-open is a safe and effective approach for carpal tunnel syndrome release. However detailed palmar hand anatomy is mandatory to prevent lesion of branching palmar nerve. The use of microscope is desirable to help identify important structures and avoid complications.
